Manual ear piercing gun

This Application is a national stage application of PCT/CN2022/076514. The present application claims priorities from PCT Application No. PCT/CN2022/076514, filed Feb. 16, 2022, and from Chinese Patent Application 202210004299.2 filed to the SIPO on Jan. 4, 2022, and entitled “MANUAL EAR PIERCING GUN”, the disclosure of which are hereby incorporated by reference in its entirety.

The present disclosure belongs to the technical field of auxiliary mounting devices for accessories, and particularly relates to a manual ear piercing gun.

Ear piercing guns have emerged for a long time. Some piercing guns generally include a gun body, an earring stud mounting part and an earring back mounting part. During ear piercing, the earring stud mounting part and the earring backing mounting part approach each other, so that the both are closer to the earlobe. The earring stud mounting part continuously moves forward, and the tip of the earring stud pierces into the earring back through the earlobe. Then, the earring stud mounting part and the earring backing mounting part move away from each other and are separated from the gun body of the ear piercing gun, and the earring stud and the earring backing are left on the earlobe. Thus, the ear piercing process is completed. Depending upon different forces for driving the earring stud, these ear piercing guns are generally classified into automatic ear piercing guns and manual piercing guns. The automatic ear piercing guns will take a short time for piercing and complete piercing instantly with less pain and are easy for operators to use. Disadvantageously, the earring stud may cause impact damage to a thicker earlobe particularly due to inertia when the earring stud fast moves through the earlobe under the action of a spring.

Therefore, the present disclosure provides a manual ear piercing gun, which can overcome the defect that an earring stud trigger spring of an automatic ear piercing gun in the prior art may cause impact damage to a user's earlobe due to inertia when the earring stud trigger spring triggers an earring stud to perform piercing.

To solve the above problem, the present disclosure provides a manual ear piercing gun, including a front gun part and a rear gun part, wherein the front gun part and the rear gun part are nested and can move linearly relative to each other; a mounting groove is formed in the front gun part, and a sliding rail member is provided in the mounting groove; a mounting slot for an earring backing mounting part is formed between the end of the sliding rail member away from the rear gun part and a side groove wall of the mounting groove; a sliding seat for mounting an earring stud mounting part is slidably connected to the sliding rail member; the sliding seat can move along with the relative linear movement of the front gun part and the rear gun part; a push rod is connected in the rear gun part; the positions of the push rod and the rear gun part are relatively fixed, and the push rod and the rear gun part can push an earring stud in the earring stud mounting part to move towards the earring backing mounting part during the linear movement of the rear gun part towards the front gun part.

In some implementations, the sliding rail member has two sliding rail arms extending towards one side of the rear gun part; a U-shaped opening structure is formed between the two sliding rail arms; the sliding seat is arranged in the U-shaped opening structure, and the sliding seat has an upper seat body in a region above the sliding rail arms and a lower seat body in a region below the sliding rail arms; and/or, the earring stud mounting part is pluggably connected in an assembly space of the sliding seat.

In some implementations, the other groove wall of the mounting groove is composed of a middle sidewall; the end of the sliding rail member close to the one sidewall of the mounting groove is fixedly connected to the front gun part; and, the free ends of the two sliding rail arms are inserted into a groove below the middle sidewall.

In some implementations, a bump is provided on the bottom side of the middle sidewall, and the bottom surface of the bump is resisted against the top surfaces of the free ends of the sliding rail arms.

In some implementations, the set mounting positions of the earring backing mounting part and the earring stud mounting part are packed in a blister box, and the blister box is removed after the earring backing mounting part is mounted in the mounting slot and the earring stud mounting part is mounted on the sliding seat.

In some implementations, the blister box has an outer flange, the middle sidewall has a horizontal wall extending towards one side of the sliding seat, and the extension length of the horizontal wall is not less than the width of the outer flange.

In some implementations, the manual ear piercing gun further includes a telescopic rod, one end of which is connected to the sliding seat while the other end of which is resisted against the wall of an inner cavity of the rear gun part through a telescopic rod spring.

In some implementations, a baffle, which is arranged adjacent to the telescopic rod and used for limiting the extension length of the telescopic rod, is provided in the inner cavity of the rear gun part.

In some implementations, the front gun part has a positioning pin, the rear gun part has a positioning groove, and the positioning pin is inserted into the positioning groove to limit the stroke of the relative linear movement between the front gun part and the rear gun part.

In some implementations, a reset spring is sandwiched between the front gun part and the rear gun part, so that the front gun part and the rear gun part can move away from each other after a user releases the force applied for the movement of the front gun part and the rear gun part towards each other.

In the manual ear piercing gun provided by the present disclosure, when a user applies a force to the front gun part and the rear gun part so that the both moves linearly towards each other, the sliding seat moves close to one side of the earring backing under the guidance of the guiding rail member, and the push rod moves with the rear gun part close to the earring stud and pushes the earring stud to pass through the earlobe and then insert into the earlobe to complete the ear piercing process. Since the positions of the push rod and the rear gun part are relatively fixed, the occurrence of impact damage caused by inertia when the push rod in the automatic ear piercing gun is triggered by the trigger spring is avoided.

With reference to, in accordance with an embodiment of the present disclosure, a manual ear piercing gun is provided, including a front gun partand a rear gun part. The front gun partand the rear gun partare nested and can move linearly relative to each other. A mounting groove is formed in the front gun part, and a sliding rail memberis provided in the mounting groove. A mounting slotfor an earring backing mounting partis formed between the end of the sliding rail memberaway from the rear gun partand one side groove wall of the mounting groove. A sliding seatfor mounting an earring stud mounting partis slidably connected to the sliding rail member. The sliding seatcan move along with the relative linear movement of the front gun partand the rear gun part. A push rodis connected in the rear gun part. The positions of the push rodand the rear gun partare relatively fixed, and the push rodand the rear gun partcan push an earring studin the earring stud mounting partto move towards the earring backing mounting partduring the linear movement of the rear gun parttowards the front gun part. In this technical solution, when the user applies a force to the front gun partand the rear gun partso that the both moves linearly towards each other (that is, the both are folded), the sliding seatmoves close to one side of the earring backingunder the guidance of the sliding rail member, and the push rodmoves with the rear gun partclose to the earring studand pushes the earring studto pass through the earlobe and then insert into the earlobe to complete the ear piercing process. Since the positions of the push rodand the rear gun partare relatively fixed, the occurrence of impact damage caused by inertia when the push rod in the automatic ear piercing gun is triggered by the trigger spring is avoided.

The sliding rail memberhas two sliding rail armsextending towards one side of the rear gun part, and a U-shaped opening structure is formed between the two sliding rail arms. The sliding seatis arranged in the U-shaped opening structure, and the sliding seathas an upper seat body in a region above the sliding rail armsand a lower seat body in a region below the sliding rail arms. Thus, the closed position (i.e., the U-shaped structure recess) of the U-shaped opening structure can limit the movement position of the sliding seattowards one side of the earring backing, thereby ensuring the consistency of the gap between the earring studand the earring backing

The earring stud mounting partis pluggably connected in an assembly space of the sliding seat, thereby ensuring the universality and reusability of the manual ear piercing gun.

The other groove wall of the mounting groove is composed of a middle sidewall, and the end of the sliding rail memberclose to the one sidewall of the mounting groove is fixedly connected to the front gun part. Specifically, a screw holethat can be fixedly connected to the front gun partthrough a corresponding screw is formed at the end of the mounting groove. The free ends of the two sliding rail armsare inserted into a groovebelow the middle sidewall. The free ends of the sliding rail armscan be limited to a certain extent by the groove, so that the position reliability of the sliding rail memberis ensured.

Since the earring stud mounting partis pluggably connected in the sliding seat, the earring stud mounting partwill drive the sliding seatto have an upward force when it is pulled out from the sliding seat, and the lower seat body of the sliding seatwill drive the free ends of the two sliding rail arms, so that the sliding arm armsform an upward bending moment, it is disadvantageous for the sliding of the sliding seatslidably connected on the sliding rail arms, and the damage to the sliding rail memberwill reduce the service life of the manual ear piercing gun. Based on this hidden trouble, a corresponding bumpis provided on the bottom side of the middle sidewall, and the bottom surface of the bumpis resisted against the top surfaces of the free ends of the sliding rail arms, so that the position stability of the sliding rail armscan be effectively ensured, and the upward deformation of the free ends can be effectively avoided.

The set mounting positions of the earring backing mounting partand the earring stud mounting partare packed in a blister box, and the blister boxis removed after the earring backing mounting partis mounted in the mounting slotand the earring stud mounting partis mounted on the sliding seat, thereby avoiding hand to contact and pollute the sterilized ear stud and improving safety. The blister boxhas an outer flange(which is about 5 mm in a specific embodiment), the middle sidewallhas a horizontal wall extending towards one side of the sliding seat, and the extension length of the horizontal wall is not less than the width of the outer flange(specifically referring to the gapin). Thus, the horizontal wall limits the position of one side of the sliding seat, and the successful alignment of the blister boxcan be ensured after the resetting of the front gun partand the rear gun partis ensured.

In some implementations, the manual ear piercing gun further includes a telescopic rod, one end of which is connected to the sliding seatwhile the other end of which is resisted against the wall of an inner cavity of the rear gun partthrough a telescopic rod spring, specifically referring to. The telescopic rodand the telescopic rod springare arranged in the corresponding transverse grooves, so that the stability and reliability during the telescopic process can be ensured. A baffle, which is arranged adjacent to the telescopic rodand used for limiting the extension length of the telescopic rod, is provided in the inner cavity of the rear gun part. It should be understood that the extension strength of the telescopic rodshould be based on the distance as a target distance between the sliding seatconnected to one end and the earring backing, and this target distance can be determined according to the thickness of the earlobe.

The front gun parthas a positioning pin, the rear gun parthas a positioning groove, and the positioning pinis inserted into the positioning grooveto limit the stroke of the relative linear movement between the front gun partand the rear gun part. The length of the positioning groovedetermines the maximum closing stroke of the front gun partand the rear gun part, i.e., the maximum stroke that the push rodcan push the earring stud

A reset springis sandwiched between the front gun partand the rear gun part, so that the front gun partand the rear gun partcan move away from each other after the user releases the force applied to the movement of the front gun partand the rear gun parttowards each other, thereby restoring the initial state of the manual ear piercing gun.

The service process of the manual ear piercing gun of the present disclosure will be further described below.

When it is necessary to perform ear piercing, a palm holds the lower part of the gun-shaped structure, and the palm contracts to compress the reset spring, so that the rear gun partmoves to the front gun part(closing process). Since the telescopic rod springis also compressed, the sliding seatand the earring stud mounting parton the sliding seatmoves close to the earring backing mounting part. At this time, it is equivalent that the earring studmoves close to the earlobe to be pierced. Aiming at the position to be pierced, the reset springis continuously compressed. When the slider moves the U-shaped structure recessand cannot move forward, the earring studreaches the position to be pierced, and the reset springis continuously compressed, and the push rodpushes the earring studon the earring stud mounting partto continuously move forward and enter the earring backingthrough the earlobe.

Since the earring backing mounting partis designed with a mechanism that the earring backingwill be separated from the earring backing mounting partwhen the earring stubis inserted into the earring backingand the earring stud mounting partis also designed with a mechanism that the earring studor its gripping membersandwill be separated from the earring stud mounting partwhen the earring studis inserted into the earring backing, so when the reset springis release, the front gun part, the rear gun partand the telescopic rodwill be reset automatically, and the earring studand the earring backingwill be separated from the earring stud mounting partand the earring backing mounting partand then left on the earlobe. Thus, the whole ear piercing process is completed.

It should be readily understood by those skilled in the art that the above advantages can be freely combined and superimposed if not conflicted.
